So max I have is $600,000, although I don't know if I want to spend all of this.My Goals:I want to scale fairly quickly, I am 35 years old now and I want to have sufficient amount of units/ properties by the age of 45.

@Norense IyahenEvery market is different to determine whether MF or SFH's are better.Normally, it is a supply / demand issue.Markets that have a lot of land area and most of the housing development is SFH's will see that the price of MFH's be higher.However, in areas with more quantity of MFH's, it may drive the price down.Furthermore, it doesn't help that every guru / real estate website is touting for investing in MFH's which is driving up the price(lowering the return).I personally invest in SFH's and have over 25.

I want to do this all while ensuring my tenants' housing needs are sufficiently met.I'm considering starting with a 5% management fee (and no extra fees), giving the first 3 months of services free as a sort of trial period, and allowing owners to back-out of my services with only a 30-day notice and no extra fees.

If the funds that you net after you complete the deal is sufficient for you to continue with your goal, then 'yes' the deal is 'good.'

Hi @Bhavik Doshi due to FHA Self Sufficiency rule it's very hard to find a 3/4 unit in the DMV that works for financing.  

Tenants seem accustomed to 1 year leases and those have been sufficient for me.

Compare your ROI and if sufficient keep it as a rental.

In the wholesaling / off-market business its all about quantity, contacting as many people as possible to get as many leads as possible.

Would a commercial lender only finance a syndication if the sponsor/MP had sufficient financial reserves or is there a way around this? 

In MA "buying a house" is not considered a sufficient reason to break the lease.
